基于我国对学生发现问题、提出问题研究的孱弱,通过课题立项研究,形成了一系列小策略:模仿发端,提出问题;搭建支架,托出问题;逆向构造,命出问题;基于开放,钓出问题;营造情境,孕育问题;基于变化,创编问题;反面切入,发现问题;类比联想,导出问题;拓展引申,萌发问题;改词易字,变出问题;否定假设,提出问题;"元认知性提问",引出问题.并辅以案例分别阐释,以助力学生的问题发现,增强学生的问题意识,提升创新能力.  相似文献

(十)总分性提问。就是所提的问题,既有总问题,又有分问题。总问题,是分问题的概括,并且包涵了分问题的全部内容。分问题,是总问题的具体化,是通向总问题的桥梁。一些教师,所以对学生“启而不发”感到苦恼,恐怕是他们提的问题不完整,不严密。就是说,他的提问,往往只有总问题,没有分问题。由是观之,所谓“启  相似文献

什么是问题教学法呢?所谓问题教学法,就是教师通过创设情景,善导问题,引导学生积极主动地在自主、合作、探究的学习过程中努力地发现问题,提出问题,探寻解决问题的途径和方法,由此获得基础知识和基本技能,学会学习并形成正确的价值观,从而完成一个教学过程的教学方法。它以问题为主线,以问题引人,以问题归结,又以新的问题引人新的学习,问题贯穿于课堂教学的整个过程之中,“问题”是问题教学法的主要特征。采用问题教学的课堂教学模式,可称之为“问题课型”或“问题教学”。  相似文献

问题教学以问题作为主线,以问题引入,以问题归结,又以新的问题进入新的学习,问题贯穿于课堂教学的始终。新课程背景下的问题教学的首要任务并不在于直接给学生传授现成的知识,而在于引导学生发现各种各样的问题。问题教学活动自始至终都应围绕问题而展开。  相似文献

伴随教育体制的变革、办学自主权的扩大,教学管理中出现的问题也越来越多,基于问题解决的“问题管理”也就应运而生。近年来,湖南省吉首市第二小学从问题人手,以问题为中心对学校实施管理,我们称它为“问题管理”,收到了良好的效果。问题管理的基本流程是:问题征集、问题整理、问题征解、问题论证、问题管理、问题管理评价。  相似文献

解决良构问题与非良构问题的研究综述   总被引:5,自引:1,他引:4  
学校情境下的问题大部分是良构问题,而现实生活中面临的问题大多是非良构问题。解决良构问题的程序是激活图式表征问题,搜寻解决方案和执行解决方案。结构性知识与具体领域的知识是解决良构问题的主要成分。解决非良构问题的过程包括了解问题的陈述,确定问题是否存在,确定问题的本质,澄清问题产生的原因,识别与澄清不同的看法,生成与选择可能的解决方案,评估与实施解决方案。认知的调节、认知观和情感态度等非认知因素均是解决非良构问题的关键因素。总之,在问题本质、问题解决过程和问题解决成分三个方面,良构问题与非良构问题存在看较大的差异。  相似文献

教育管理学的研究对象是教育管理问题或成为问题的教育管理现象。根据教育管理问题的性质,可从不同的角度把教育管理研究的问题分为事实问题与价值问题、经验问题与概念问题、常规问题与革命问题。所有这些问题必须是真问题,而不是假问题。  相似文献

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F.  相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?  相似文献

Different nations have different social cultures, and the social culture of every nation is developing with the development of the nation, language is greatly influenced by social culture, which enables language to possess national and historical characteristics. Word is the smallest, independent, meaningful linguistic unit of language. It can well reflect the national and historical characteristics. From synchronic aspect, the social and cultural influence on word meaning is mainly embodied in conceptual and associative meanings of word. The incorrespondence of word meaning is a phenomenon that exists in both conceptual and associative meanings of word among different languages. From diachronic aspect, the development of social culture causes some changes of word meaning to some extent. Therefore, social culture plays a key role in vocabulary learning and mastery of a language.  相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.  相似文献
